To locate a data item for storage is Fetch. In computer technology, fetch has several meanings related to getting, reading, or moving data objects. Fetch, area of ocean or lake surface over which the wind blows in an essentially constant direction, thus generating waves.

Semiconductor memory is a digital electronic data storage device, often used as computer memory, implemented with semiconductor electronic devices on an integrated circuit. There are many different types of implementations using various technologies.

The main purpose of time sharing techniques used in computers is to make the best use of the CPU. Timesharing allows a central computer to be shared by a large number of users sitting at terminals.

The immediate processing It can occur with either sequential of direct-access files. The computer is said to be processing no matter what action it is taking upon the data.

In computer science, a data buffer (or just buffer) is a region of a physical memory storage used to temporarily store data while it is being moved from one place to another.

An arithmetic logic unit (ALU) is a combinational digital electronic circuit that performs arithmetic and bitwise operations on integer binary numbers. This is in contrast to a floating-point unit (FPU), which operates on floating point numbers.

John von Neumann (December 28, 1903 – February 8, 1957) was a Hungarian-American mathematician, physicist, computer scientist, and polymath. He made major contributions to a number of fields, including mathematics (foundations of mathematics, functional analysis, ergodic theory, representation theory, operator algebras, geometry, topology, and numerical analysis), physics (quantum mechanics, hydrodynamics, and quantum statistical mechanics), economics (game theory), computing (Von Neumann architecture, linear programming, self-replicating machines, stochastic computing), and statistics.
